Certifi is a carefully curated collection of Root Certificates for
validating the trustworthiness of SSL certificates while verifying the
identity of TLS hosts. It has been extracted from the
Requests project.

The internet is an untrusted place. Every HTTP request you make should have
verification on by default. This happens every time you access a website with
your web browser, without any knowledge to the user — there’s no reason your
code should be any different.
